Popularity wouldn’t be my initial reason for considering a particular luxury car, exclusivity higher on my list of desirable attributes. Still, the object of one’s eye needs to have achieved a certain level of marketplace acceptance in order to drive demand among pre-owned buyers or its resale value will plummet as soon as you drive it off the lot. That’s just one reason why the [Jaguar XJ](http://www.carsoup.com/for-sale/Jaguar/XJL/) makes sense.

It’s no S-Class when it comes to the full-size F-segment luxury sedan sales chart, or BMW 7 Series for that matter, these two models finding 11,974 and 8,038 sales respectively over the first eight months of 2016, but Jaguar’s 2,452 XJ deliveries come close to matching the 3,768 sales of Lexus’ LS and 2,616 of Audi’s A8. If you think these numbers sound small, consider for a moment that Acura only sold 951 examples of its RLX over the same period, whereas premium wannabes Hyundai and Kia only sold 1,237 and 553 of their Equus and K900 respectively, although to be fair to the former Korean sold 2,332 units the year before (when the XJ sold 3,611) and 3,415 throughout 2014 (12 months that the XJ found 4,329 buyers), its sales winding down ahead of the new Genesis brand and its flagship G90 introduction.

This brings up another point, high-end luxury buyers want real heritage and pedigree. While the new G90 looks like a fine car, its success in this class will need to be earned over time. For example, the LS nameplate has been around since the dawn of Lexus in 1989 when it arrived alongside the now defunct Infiniti Q45, and thanks to unparalleled reliability, excellent build quality and improvements in style, performance and brand cachet it’s now a serious contender. Jaguar as a brand doesn’t pull anywhere near Lexus’ sales numbers, even when lumping in Land Rover, but just the same the XJ has swagger in this segment because it not only precedes the LS by decades, but all other competitors too.

Jaguar introduced the XJ in 1968, four years before the first S-Class would hit the autobahn and nine years ahead of Munich’s much larger Bavaria replacement, while the Audi A8 wouldn’t come along until 1994. Of course, the Mercedes-Benz brand, at least, had large luxury sedans available since the mid-’20s, whereas Jaguar was formed from the SS brand in 1945, but it was merely a name change for a company that had been building luxury cars for much longer, and the rest, as they say, is history. But this is exactly my point. Deeply rooted history is something the rest, other than Cadillac, can’t draw upon, and the American brand doesn’t really build a true F-segment competitor (that model will be the CT8, if it ever sees the light of day).

Speaking of Cadillac, which just introduced a car that might woo some buyers away from today’s standard of the world brands (albeit the 4,048 CT6 models sold during the last six months of 2016 probably went to CTS owners), has had to make its mark with ultra-low $53,495 base pricing. Even the new Genesis will start at $68,100 when it arrives in November, whereas the XJ is still a superb value at $74,400 when factoring in the much less advanced LS that starts at $72,520, the all-new 7 Series at $81,500, the stylish A8 L at $82,500, and the always impressive S-Class at $96,600 (in case you were wondering a 2016 Kia K900 can be had for just $49,000).

What’s so advanced about the XJ? The majority of its body and chassis is constructed of lightweight aluminum, the only other car in the class to do likewise being the A8 (and slightly smaller CT6). Granted, BMW’s pricey 7 can be judged as even more advanced thanks to a body structure composed of carbon-fiber-reinforced polymer (CFRP), high-tensile steel and aluminum, while Merc’s new S-Class is hardly backwards thinking thanks to a high-strength steel and aluminum monocoque, none comes close to the XJ’s street fighting curb weight. Only the narrower Caddy weighs less, the XJ slightly lighter than the A8, and hundreds of pounds less than the more comparable S and 7. When you start comparing the weights of the long-wheelbase varieties the XJ’s performance and efficiency advantages increase commensurately.

Added to that, the XJ’s riveted aluminum monocoque chassis and body structure achieves near equal front-to-rear weight distribution for superb balance, while its also incredibly strong and rigid, which aids handling further, as well as allowing for more compliance from its adaptive air suspension for better ride quality, plus improved crash protection and the ability to utilize more than 50 percent recycled Al. As for its lighter weight contributing to fuel economy, the base XJ RWD is rated at 18 mpg city, 27 highway and 21 combined, while the same engine with AWD gets a claimed 17 city, 25 highway and 20 combined; both sets of numbers very good for the class. Sound like a win-win-win-win-win? It is.

The result is a full-size luxury sedan that feels as substantive as anyone could want during high-speed highway cruising, but when straight turns to curve and opportunity for some switchback fun arises the XJ is one of, if not the most engaging in its class. I’d have to test them all back to back on the same stretch of road in near identical conditions to know for sure, because most of the cars mentioned above are capable through the corners, and I’d love to try out the new for 2016 electric power steering in RWD XJs (AWD models carry forward with hydraulic power steering), but there’s a liveliness to the fast cat that makes the rest seem like bumbling sheepdogs. OK, maybe that’s a bit of a stretch, but you get my point.

Of note, the air suspension I mentioned earlier is Jaguar’s Adaptive Dynamics system that monitors speed, steering input, body movement and more up to 500 times per second, while continuously modifying damping rates to enhance performance and comfort levels.

Less weight also results in a better power to weight ratio, which means the XJ’s dynamic engine duo are allowed to perform to their maximum potential. That would be 340 horsepower and 332 lb-ft of torque for my 3.0-liter supercharged V6 tester, or alternatively 470 to 550 horsepower and 424 to 502 lb-ft of torque from the Supercharged and sportiest XJR models respectively. Other than to mention both engines utilize a state-of-the-art eight-speed automatic with manual mode, paddle shifters, JaguarDrive Control driver-selectable efficiency, Dynamic sport and winter modes, auto stop/start, RWD or all-weather “Instinctive” torque vectoring AWD with All Surface Progress Control (ASPC) developed from Land Rover’s Terrain Response system for tackling slippery situations, resulting in zero to 60 mph sprint times of from 6.1 to 4.4 seconds, as well as top speeds of 121 to 174 mph, I’ll leave comments about the latter cars for future reviews, and instead focus on the version in hand.

With Jaguar’s motorsport proven performance pedigree safely intact, and Ian Callum’s stunning exterior styling so obviously above par that my mumblings could hardly do it justice other than to say the 2016 model receives a mild refresh including a nicely reworked grille and lower fascia incorporating larger corner ducts, standard LED headlamps with J-shaped driving lights, oval exhaust pipes, and other small details, the majority of updates were focused on the interior, particularly the fully reconfigurable TFT primary gauge cluster that receives higher resolution, quicker response, better graphics, and the ability to display navigation mapping across the whole screen, plus the infotainment system atop the center stack.

InControl Touch Pro is much more intuitive design than the previous interface, as it works more like a smartphone or tablet thanks to finger gesture capability such as swiping and pinching, while it also incorporates a much faster and more shock resistant solid-state hard drive, plus a more powerful quad-core processor. Additionally, the wireless connectivity works better and voice control now allows full dictation of addresses for easier use of the navigation system. What’s more, once the system gets to know you it will suggest alternative routes to escape traffic congestion. Possibly its best update is a $1,050 optional surround parking camera system that not only displays a bird’s-eye view of the surrounding area, but when you’re 650 feet away from your preprogrammed destination the monitor will attempt to direct you to available parking spaces; front and rear parking sensors are also part of the package. Lastly, a new smartphone app will prep your XJ before you get there by starting the engine and adjusting the climate control, or if you can’t find your car it’ll locate it and then unlock the doors upon your arrival. There’s much more to the app and InControl Touch Pro system, but rather than going into every last detail hopefully you’ve been inspired to have some fun with it.

All of these features were standard with my $86,700 XJL AWD Portfolio (the “L” tagged onto the XJ nameplate being short for LWB or long-wheelbase, which adds five inches of rear legroom), although the aforementioned 360-degree parking camera and sensors were upgraded as were the brilliant set of 20-inch polished Orona alloys on 245/40R20 front and 275/35R20 rear P Zero Nero rubber for $3,000, a $375 heated windshield, a $500 heatable wood and leather-rimmed steering wheel, $700 worth of powered rear side sunshades, and $626 for branded rubber floor mats and wheel locks, the revised total being $92,951 before freight and fees.

Of course, plenty of additional options could have been added, a rear entertainment system noteworthy due to dual 10.2-inch displays that fold 180 degrees into the seatbacks when not being used. You can also get a $1,700 Illumination Pack that adds illuminated tread plates and trunk finisher, phosphor blue illumination in the front and rear air vents, and rear LED reading lights; and an $8,500 Premium Rear Seat Package that removes the regular flip-down center armrest seat and replaces it with a much more advanced one with integrated controls for the upgraded individually powered bucket seats with memory that also massage in three different styles, while retractable business tables and rear seat entertainment also get added. I’d also have to add the $4,200 26-speaker, 1,300-watt Meridian Reference Audio System, and not because of its unique conversation assist system, but rather for conversation blocking music nirvana (not necessarily the band, although some Seattle sound would be just fine too). Adaptive cruise control is usually a must-have too, but $1,595 is a steep price to pay merely for this feature, even if it includes stop-and-go. This reminds that the XJ can’t be had with the latest active safety mitigation features such as autonomous braking, lane keeping assist, etcetera, which means it doesn’t qualify for IIHS Top Safety Pick Plus status (it won the Strategic Vision Total Quality Award, mind you, kudos to Jaguar for that).

And did I mention how beautifully everything inside is put together? All the leathers upon contrast stitched leathers plus sumptuous psuede, premium soft touch surfacing, planks of burled walnut, brilliantly polished metals with some even knurled to jewel-like perfection, only a tasteful amount of piano black lacquer, and superbly crafted switchgear with nice, tight, well-damped fitment, the interior is as opulently finished as the exterior is breathtakingly beautiful. A simple black-faced analog clock is the ideal classic touch, and the JaguarDrive Selector continues to thrill all those uninitiated souls who haven’t seen something so beautifully sculpted power up out of the console, its practical and space saving applications also best in class.

As you can imagine the extra rear space of this LWB model was overkill for my five-foot-eight height, although an enjoyable enough place to kick back and take notes let alone be chauffeured through town in. I wouldn’t be asking my driver to take me to the ski hill, however, as Jaguar doesn’t provide a pass-through to expand the usefulness of its otherwise large and accommodating 15.2 cubic-foot trunk, but such is not unusual among truly elite luxury sedans. After all, Jaguar now makes the F-Pace SUV for such activities, or you can opt for a full-size Range Rover, which is more in the XJ’s league.

After time well spent in this most recent 2016 XJL I’m once again reminded that few of its luxury sedan peers fully measure up. As noted there are many that try, but when it comes to spellbinding styling, rich opulence, and jaw-dropping performance the XJ is hard to beat, while it holds its own in most every other category too. It’s not the least expensive in its class, but when factoring in its standard features set and reasonable pricing for most options the XJ offers up good value.
